Digital watermarks can help secure critical documents, whether they're business documents, creative property, or personal records. A-PDF Watermark adds digital watermarks to PDF files, singly or in batches. Watermarks can be logos, text, a date/time stamp, page number, image, and more. The program can also label the file's status, stamp files, and enable watermark manipulation within PDFs. It can even import and export watermarks and print without saving, two enterprise-class features.
A-PDF Watermark's interface is typical of recent Windows apps, a clean, efficient, familiar setup that, together with PDF-based Help file and demos, makes this program easy to learn. There are three ways to add watermarks from A-PDF: The main interface, automatically via the watched folders feature, and from the Command Prompt. We browsed to a PDF, selected the date/time stamp watermark, and clicked Append Watermarks to PDFs. The program instantly responded with a small "done" pop-up. There are controls for associating watermarks with an email client, printer, or FTP, too. The Hot Directory Mode is especially intriguing: It's a simple dialog that sets the program to add a watermark to any files in a specified directory. Creating a new watermark is just as easy, and actually fun, too, thanks to a feature-filled dialog with a preview pane. We whipped up a properly sized image watermark from a random JPEG, saved it, and applied it to a PDF in mere seconds.
It's difficult to imagine anything related to PDF watermarks that A-PDF Watermark can't handle. It's fast, easy to use, flexible, and effective, and highly recommended.Editors' note: This is a review of the full version of A-PDF Watermark 3.3.0. The trial version has a demo watermark on output.
